Way back in 1998, lawmakers up in Northern California's Alameda county passed a gun control ordinance for unincorporated areas within the county.
It prohibited new gun shops within 500 feet of residential neighborhoods, schools, liquor stores, or another gun shop.
Shop owners sued, charging that the county was restricting the constitutional rights to buy and sell firearms.From there, things got complicated. The case was dismissed, reinstated...and yesterday a federal appeals ordered yet another rehearing.
All this is important to gun rights advocates and to proponents of gun control - because there are similar ordinances in a lot of other California cities and counties.
The San Francisco Chronicle's Bob Egelko, who has written about this, spoke to A Martinez for more.
